ouis Oosthuizen takes two-shot lead into the third round of the 149th Open after recording the lowest halfway total in championship history at Royal St George’s. The former champions fired an eagle and four birdies to chase down American pace-setter Collin Morikawa then surpass him to go 11-under.
World number one Dustin Johnson warmed to the task with a menacing five-under 65 moving him to seven under while Germany’s Marcel Siem, Argentina’s Emiliano Grillo, who matched Morikawa’s 64, and Englishman Andy Sullivan were all on six under.
US Open champion Jon Rahm muscled his way up the leaderboard with a faultless 64 to move six off the pace along with Brooks Koepka and England’s Paul Casey.
Northern Ireland’s Rory McIlroy, seeking a first major since 2014, made the cut on even par after a second successive 70 while Bryson DeChambeau shrugged off his spat with his driver manufacturer to scrape into the weekend on one over.
